What: The actress wins in Western at the launch party for The World of Gloria Vanderbilt held at the Ralph Lauren Women's Boutique in New York yesterday.

Wear: A Ralph Lauren look from the spring 2011 collection

Camilla Belle celebrated the publication of Wendy Goodman's tribute to Gloria Vanderbilt at the Ralph Lauren Women's Boutique last night alongside Uma Thurman and Sarah Jessica Parker. Despite the drop in temps, the twenty-four-year-old actress showed off her gorgeous gams in a Western-inspired fringe skirt from Ralph Lauren's spring 2011 collection (see it on the runway). Belle stars in upcoming film From Prada to Nada (the trailer for which just released this week—watch it here), playing one of two wealthy-turned-penniless sisters who move in with their aunt in East L.A.
